"I'm making this heads-up challenge to the world. Anyone can accept. Four tables, minimum of $200/$400, and I'll put up $1.5 million to their $500,000. We play 50,000 hands minimum and if they end up a dollar after rake they keep the side money or whatever. So basically, if you and I played and you won a dollar, you would get my $1.5 million and if I won a dollar I would win your $500,000.

"So I'm giving a million dollars free if anyone thinks they can do it."

Dwan later made a post on 2+2 in which he clarified the proposed terms of the challenge:

"1) 200-400min (nl/plo obv)
2) can change tables anytime eff stacks are >250bb
3) have to reload when stacks are <75bb
4) $$ won in the challenge is kept obv (if i win 750k in poker, i get that PLUS your 500k- if i lose 750k in poker you get 2.25m total).
5) same stakes the whole time
6) not open to phil galfond"

It will be interesting to see who responds to this challenge.

I can't see a player like Phil Ivey or Patrik Antonius turning an offer like this down.

Phil "OMGClayAiken" Galfond is excluded from the competition, as per Dwan's post on 2+2.

After Ivey and Antonius, you start to run out of potential candidates.

Either of the Dang brothers? Ilari "Ziigmund" Sahamies? David Benyamine?

It will be interesting to see who, if anyone, takes Dwan up on this offer.
